Bai Song began to envy the protagonists of those reasoning.

In reasoning, it is only necessary to reason out the correct answer, and then find a few unique evidences, and the criminal will panic, gradually give up resistance in the confrontation, and admit what he has done.

But the reality is really...

Yao Lei actually died like this, and the cause of death was directly stabbed to death by Yao Xin.

The problem is that, judging from the current situation, Yao Xin is likely to be innocent.

...

The two cars quickly arrived at the scene, Yao Xin had been taken away at this time, on the one hand, to collect body fluids, and on the other hand, she had to be questioned.

However, Bai Song heard that Yao Xin was already a little insane and in a trance, and he should be frightened.

...

This is the first time Bai Song has seen Yao Lei, but he has already fallen in a pool of blood.

"What's the situation on?" asked Bai Song.

When the criminal policeman Xiao Zhao saw Bai Song, he hurriedly said: "Inspector Bai, Yao Lei was stabbed four or five times, looking at the place where he was stabbed, he was basically stabbed indiscriminately, but there were two knives in the stomach and lungs, after Yao Xin called the police, the 110 platform also notified 120." When 120 came, Yao Lei was already dead. ”

"The cause of death was excessive bleeding?" Bai Song asked.

"That's right. Xiao Zhao said.

"Did the two of them drink or take drugs?" Bai Song asked.

"No, judging from the scene, the two did happen... And Yao Xin's resistance is obvious. ”

"What kind of injury is Yao Xin?"

"Multiple soft tissue contusions. ”

"What's her state?"

"I feel like I'm having a nervous breakdown. ”

"Did Yao Xin bleed?"

"Bleeding? Soft tissue abrasions, there must be some bleeding. Xiao Zhao wondered.

"I'm not talking about bleeding. "White Pine is still serious.

"Huh?" Xiao Zhao was stunned, not understanding what he meant.

An old forensic doctor next to him heard this, took Bai Song's words and said, "There is no bloodshed." ”

"Well, thank you. Bai Song nodded, signaling that he was fine.

...

Xijing Branch, Conference Room.

"I agree with Inspector Bai's reasoning. Detachment Liu said again: "But in that situation at the scene, a little butene, butane or anything could not be collected, the bottles were all broken, and even the wine was roasted." Originally, there were some special substances in the wine, and even if it was burned dry, there were traces, but after the high-pressure water cannon extinguished the fire, there were no traces that could be taken. ”

"This case..."Zhuang Detachment said: "Now, it can basically be considered that Yao Xin wants to use Yao Lei as a substitute for Yao's death." Yao Lei also brought two bottles of wine, which is estimated to have been instructed by Yao Xin, and Yao Lei did try to take Yao's money, and it is estimated that Yao Xin instigated it, and now, Yao is dead like this, this matter..."

Yao Lei and Yao Xin both brought two bottles of wine, and now the trouble is here. And now it's so cold, and the clothes are relatively thick, and the monitoring can't see if there are any small pieces hidden in the clothes.

Speaking of this, the Zhuang detachment looked at everyone: "This matter is already like this, Yao Xin must be controlled, Yao Lei's autopsy is estimated to have no valuable clues, now everyone speaks freely, don't be afraid to say the wrong thing." ”

"The motive for the killing is probably simple. Bai Song said directly: "This Yao and Yao Lei are definitely not good things." Yao Lei was able to do this to Yao Xin without drinking alcohol or taking medicine tonight. Even if Yao Xin used some means, this means that this is not the first time. As for Yao Xin's silent character, who can deliberately murder Yao, and even plan for a long time, I think Yao must have had similar behavior towards Yao Xin. ”

"I agree with that. Zhuang said: "This should be the motive for the crime." ”

Such tragedies are not uncommon, and many people are not worthy of being fathers at all.

If there is such a history, it is normal for Yao Xin to form his current character, and this murder is estimated to have been designed for a long time. The good girls for so many years have basically been obedient and acting!

Even, Bai Song had no doubt that Yao Xin had told Yao that he had invited someone to drink the night before the incident. Although Yao didn't listen to Yao Xin's words very well, Yao Xin was moved by affection and reason, and it was still easy for his father to invite workers to eat and drink on his birthday before the start of the new project.

Now the situation is, where do you find the evidence?

"Is there a problem with the justified defense on the spot?" the Liu detachment asked.

"The Wei Bureau will come over in a while, let the leader have an idea. The Zhuang detachment looked at its watch, at 3:40 a.m., and continued: "It's already on the way." ”

"Good. ”

...

After a short silence, Bai Song said: "There is still a lot of evidence to check. First of all, where did Yao Lei buy the wine? Now it is basically possible to deduce what Yao Xin did, Yao Xin has been planning for so long, and many things are estimated to have been taken precautions, but she can instigate Yao Lei, but she can't completely decide what Yao Lei does. We can check where Yao Lei bought wine, and then chase the surveillance, maybe we can wash away Yao Lei's suspicion. In addition, Yao Xin must have thought that fire could destroy everything, but there are still loopholes, such as styrofoam, and we need to find Yao Xin's record of buying styrofoam. ”

"Styrofoam?" Detachment Liu wondered, "Inspector Bai, what's going on with this?"

Only then did Bai Song think that this information was not shared.

Detachment Liu obviously heard that this was an important piece of information, but Bai Song was very disrespectful when he said it now. Although Bai Song is a superior department, intelligence sharing is the way it should be.

After thinking about it, Bai Song told the process of discovery, and then said: "I have some friends in the criminal department, and I found someone to do a test overnight, and I just learned that it was styrofoam, which is used to make seals, and the location found is very wrong." Of course, if the two windows didn't fit tightly, they would not have been burned by fire and washed away by water. ”

"Inspector Bai's subordinates are really strong generals. "Detachment Liu naturally knew that Bai Song had forgotten to tell them this, but as soon as Bai Song explained this, that is, he had gone down the steps, and he would definitely not pursue it. It's all decades of work experience, this kind of thing is too normal, but he has to have this prestige in the conference room.

"It's kind of accidental. Bai Song said: "The glass of the two windows is broken, but the aluminum alloy is still relatively strong. ”

"Okay, we have to do our best to investigate this, including the places where Yao Xin didn't go home at night before, and it is estimated that this is where she fractionated butene and butane. Liu Detachment said: "In addition, does Inspector Bai have anything to add?"

"Liquefied petroleum gas is not only sold at liquefied gas stations, many portable hot pots also exist in small jars of liquefied gas cylinders, this is very easy to buy, we need to investigate a large extent. Bai Song said.

Detachment Liu looked at Bai Song, nodded, and did not speak.
